BIRD CAGE.

Application filed November 22, 1926. Serial No. 149,881.

and others that will appear as the nature of the invention isbetterunderstood, the same consists in the novel construction, combina tionand arrangement of parts hereinafter more fully described, illustratedin the accompanying drawing and pointed out in the appended claims.

In, the drawing forminga part of this application andin which likedesignating characters refer to corresponding parts throughout theseveral views,

Fig. 1 is a top plan View of the base and tray of the cage, with cageproper'or dome partly removed;

Fig. 2 is a cross-sectional view through the base and the tray'andthrough a fraction of the dome or cage proper;

Fig-3, is an enlarged view of one of the locking means associating withthe tray for locking the dome thereto;

Fig. 4 is an enlarged cross-sectional view of one of the locking meansshowing the operation thereof; and

Fig. 5 is a view partly in elevation and partly in section taken on line5+5 of Fig. 4

therein. a .ase generally indicated by 1 having a bowl-lilire portion 2from which radiates a horizontal portion constituting shoulder 3 fromwhich the annular upright portion 4 projects. From said annular up rightportion 4 flange or rim 5 flares out on substantially horizontal plane.Cooperating with said base is atray (Shaving a curved portion 7 which isadapted to closely fit within the bowl-like portion 2 of base 1. Saidtray further embodies a horizontal flange 8 which flares out from saidcurved portion 7 of the tray and is adapted to rest upon the shoulder 3of the base.

The cage proper or dome embodies'a plurality of wire strands 9 which arearranged in a round formation as is clearly apparent from Fig. 1. Thelower ends of said wire strands 9 are held in position by annular band10 wherein the wire strands 9 are frictionally heldwithin loops 11struck out Referrin to the drawing there is shown,

in said band; Said band is receivable within the annular upright portion4 0f the base 1 and normally is adapted to rest upon the flange Set thetray 6 upon shoulder 3 of the base 1.

Flange 5 of base 1 adjacent the annular upright portion 4 thereof has atongue 12' which is secured under said flange 5 by means of rivets 13.Said tongue passes through said annular upright portion 4 adjacent saidflange 5 and projects inwardly of the tray and overhangsshoulder 3 ofbase 1. Normally when the dome is within the base said tongue overhangsthe annular band 10 and prevents itsuprightshifting with respect to thebase. On a line diametrically opposite from said tongue 12 the base isprovided with a shifting locking means embodying lip 14 which passesthrough the slit 15 made in'the upper edge of the annular uprightportion 4 of base 1 and adjacent flange 5. Said lip is integrally formedwith an arcuate plate 16 which normally rests upon and abuts the outerperiphery of said annular upright portion 4 and to which it isriveted'by its other end as at 17. Said plate 16 adjacent its rivetpoint 17 is provided with a rigidly formed horizontalextension 18'whicliprojects from the upper edge of saidplate 16v Normally said extension 18abuts the lower face of flange 5 and by means of-rivet 19 it is securedto said flange 5, for further holding plate: 16 in position; At itsother termination and-beyond lip 14 said plate 16 is further providedwith an integrally formed L-shaped plate 20 constituting a hook bymeansof which plate 16 may be angularly shifted away from the annularupright portion 4 of the base 1.

7 It is observed that said plate 16 is of a resilient springy materialby reason of which fact it closely abuts the outer periphery of theannular upright portion 4 and by reason of which fact lip 14 normallyprojects beyond the inner periphery of said annular upright portion 4and overhangs annular band 10, flange 8 of tray 6 and shoulder 3 of base1.

Radially in respect of the base 1 lip 14 g has downwardly struck out rib21 which frictionallv engages the upper edge of aninularband 10 forpreventing shifting of the dome with respect tothe base, whicharrangement will also prevent rattling of the The up.

per edge of said annular upright portion 4: of base 1 at a point belowsaid rib 21 is provided with slot 22 within which said rib 21 isaccommodated and within which it is adapted to make sliding movementwhen the lip 14 is shifted out of its normal position by means of handle20. 7

To remove the dome from the base, plate 16 is manually shifted fromannular upright portion 4 by means of handle 20, which operation willwithdraw lip 14 from its normal position best shown on Fig. 1 and willpass the same beyond the outer periphery of the annular upright portion4. Then the portion of band 10 with the dome adjacent said lip 14 may beraised for Withdrawing the same from within said annular upright portion4:, flange 8 and shoulder 3 for removing the. same from within the baseas is apparent- It is further observed that in the operative associationof the dome with the base, tongue 12 and lip 14: remain within therespective'adjacent pairs of wire strands 9, which arrangement preventsthe rotary shifting of the dome with respect to the base.

\Vhile there is described herein a preferred embodiment of the presentinvention, it is nevertheless to be understood that minor changes may bemade therein, without departing from the spirit and scope of the invention as claimed.

What I claim as new is:

1. Means for attaching a bird cage to its base comprising afixed-fastener carried by the base and engaging the cage, and a catch.

device formed of spring metal and attached to the base at plural pointsat substantially right-angles to each other to distribute the strain attheipoints of attachment to'the base when the fastener is flexed, saidfastener having a lip adapted to engage the bird cage to retain the sameon the base.

2. Means for attaching a bird cage to its base comprising an elongatedsprlng metal ng in opposite directions, said horizontal extensionadaptedto be attached to the cage 7 base and said lip adapted to engagethe bird cage to hold the same on the base, and an L-shaped extension onsaid member forming a handle for flexing the same to release said lipfrom the bird cage.

3. Means for attaching a bird cage to its base comprising an elongatedspring metal member having a pair of lips formed integrally therewithand located each adjacent an end of said member and bent to extend inopposite directions, one of said lips adapted. to be attached to thecage base and the other lip adapted to engage the bird cage to hold thesameon the base, an extension'on said member forming ahandle for flexingthe same to release said latter named lip from the bird cage, and saidlast named lip formed with a rib constituting a centering device for thecage with respect to its base. 1

i. A bird cage comprising a base having a shoulder and a rim, awire'strand dome, an annular band engaging the-lower ends of the wire strandsof said dome, a tongue upon. said rim normally overhanging said annularband and being disposed between a pair of adjacent wire strands, alip atsubstantially diametrically opposite point from said tongue inassociation with said rim, said lip normally overhanging said annularband and being disposed between a pair of adja cent wire strands, saidrim at itsrbase portion having a slit through which said lipis adaptedto shift, a downwardly projecting rib formd in said lip forfrictionally. engaging the upper edge of (said annular band whensaid lipis in operative position, and means upon'said lip for withdrawing thesame from engagement? with said annular band. 1 i j j i In testimonywhereof I affix my signature ANTON M; KROCZEK.
